A small watercraft 1 according to an embodiment of the present invention is described with reference to FIGS. 1 to 23.

As illustrated in FIGS. 1 to 8, the small watercraft 1 is a small watercraft for leisure use, and is used for sports, recreations, and the like. For example, the small watercraft 1 has an overall length of approximately 12 m, a weight of approximately 10 tons, and a complement of 12 persons. The small watercraft 1 includes an engine (not illustrated), and is configured to obtain thrust by driving a propeller (not illustrated) with the engine serving as a power source.

As illustrated in FIGS. 1 to 10, the small watercraft 1 includes a deck 1 b on an upper side of a hull 1 a and a cabin 1 c on an upper side of the deck 1 b. The small watercraft 1 includes a lounge space 8 and a pilot house 2 that are in the cabin 1 c. The small watercraft 1 has a width of the deck 1 b smaller than a width of the hull 1 a, and side portions of the deck lb positioned more on the inner side than side portions of the hull 1 a. The hull 1 a and the deck 1 b of the small watercraft 1 are mainly made of an FRP material. Outer shapes of the hull 1 a and the deck 1 b are formed by spraying gelcoat on a mold coated with a release agent (wax), and after the gelcoat is dried (cured), stacking layers of glass fiber roving, unsaturated polyester resin, and the like until a designed thickness is achieved.

Configurations of components of the small watercraft 1 are described in detail below.

The hull 1 a of the small watercraft 1 is provided with the deck 1 b, the cabin 1 c, an engine room 1 d, a radar arm 1 e, a pair of left and right air introduction ports 1 f, 1 f, a rear deck 1 g, and a transom gate 1 h.

The deck 1 b covers an upper part of the hull 1 a and forms a compartment and the like. The deck 1 b is provided with a plurality of windows (a front roof window 11, a rear roof window 12, and a pair of left and right side windows 13, 13) for daylighting in the compartment in the inboard section and a mooring device 22.

The front roof window 11 and the rear roof window 12 are widows for daylighting in the inboard section. The front roof window 11 is disposed at a portion of the deck 1 b more on the front side than the cabin 1 c and on a bow side of the deck 1 b, in a non-openable (fixed) state. The front roof window 11 is disposed at a portion that is separated from the bow by a distance corresponding to approximately one fifth of the hull length.

The rear roof window 12 is disposed at a portion of the deck 1 b more on the front side than the cabin 1 c and on a stern side of the deck 1 b, in an openable state. The rear roof window 12 is separated from the bow by a distance corresponding to approximately two fifths of the hull length. The rear roof window 12 can be opened by an opening angle that is larger than 90° about a stern side portion. The rear roof window 12 is configured to be tightly closable with a plurality of unillustrated fasteners. The rear roof window 12 in an opened state can be used for ventilating the compartment, for going to and coming back from a bow deck (deck 1 b), or for other like purposes. More specifically, an unillustrated ladder supporting unit is formed on a window frame of the rear roof window 12. The rear roof window 12 is configured in such a manner that, in the opened state, a ladder 100 can be supported by the ladder supporting unit.

The ladder 100 to be used is configured to be extendable and retractable, and is contained in a container box 53 in an owner room 3 described later (see FIG. 15). The ladder 100 is configured to be taken out from a side surface opening 53 b of the container box 53 to be used. The present embodiment is not limited to the ladder 100, and a gangway may be used.

As illustrated in FIGS. 1 to 4, 9, 15, 17, and 18, the side windows 13, 13 of the small watercraft 1 are disposed on left and right side portions of the deck 1 b. The side window 13 is disposed to extend from an approximately center portion in a bow and stern direction to a portion that is separated from the bow by a distance corresponding to one fifth of the hull length. The pair of left and right side windows 13 each have an inboard section side divided into two sections of a bow side window 13 a and a stern side window 13 b. The pair of left and right side windows 13 each have the bow side window 13 a serving as a window for the owner room 2 and the stern side window 13 b serving as a window for a salon 4 and a galley 5.

The small watercraft 1, divided into the bow side and the stern side at the cabin 1 c (pilot house 2), is relatively longer on the bow side. Thus, the small watercraft 1 can have a space large enough to dispose the front roof window 11 and the rear roof window 12 (a space large enough to dispose two roof windows on the deck 1 b arranged in the bow and stern direction). Thus, the small watercraft 1 can have the pair of left and right side windows 13 that are large in the bow and stern direction.

As illustrated in FIGS. 1 to 10, the cabin 1 c protrudes beyond the deck 1 b to cover the rear side of the deck 1 b, whereby the pilot house 2 and the lounge space 8 are formed. A person can go into and come out from the cabin 1 c through a gateway 1 i of the rear deck 1 g. The cabin 1 c includes a windshield 14, a pair of left and right side windows 15, 15, a movable roof 16, and a window door 45 serving as the gateway 1 i of the rear deck 1 g. The cabin 1 c has an opening formed in a roof portion.

As illustrated in FIGS. 1, 5, 7, and 13, the windshield 14 of the cabin 1 c is disposed across left and right end portions of the pilot house 2.

The windshield 14 has a left and right direction width that is approximately the same as a left and right direction width of the pilot house 2. Thus, the small watercraft 1 features a better view from a helmsman seat 21 a in the pilot house 2 compared with a configuration without the windshield 14 disposed across the left and right end portions of the pilot house 2.

The movable roof 16 is provided in the opening formed in the ceiling portion of the cabin 1 c. More specifically, the movable roof 16 is disposed above the helmsman seat 21 a and an assistant helmsman seat 21 b. As illustrated in FIGS. 21 and 22, the movable roof 16 includes a fixed portion 16 a and a movable portion 16 b, and is openable and closable through sliding movement of the movable portion 16 b. The fixed portion 16 a and the movable portion 16 b of the movable roof 16 are each formed by fitting a glass piece on a frame. The movable roof 16 has crosspieces 16 c formed in the movable portion 16 b to achieve high glass strength. Thus, the movable portion 16 b of the movable roof 16 can stably operate.

The window door 45, serving as the gateway 1 i, is provided at a center portion of a stern side end portion of the cabin 1 c. The window door 45 is formed as a sliding door that moves in a left-and-right direction to be opened and closed. The window door 45 is entirely glassed. The fixed portions on both left and right sides of the window door 45, at the stern side end portion of the cabin 1 c, are glassed.

The small watercraft 1 includes the engine room 1 d, the radar arm 1 e, the pair of left and right air introduction ports 1 f, 1 f, the rear deck 1 g, and the transom gate 1 h.

An engine is disposed in the engine room 1 d of the small watercraft 1.

The engine room 1 d is provided in a space (inboard section) surrounded by the hull 1 a and the deck 1 b. The engine room 1 d is disposed below the cabin 1 c. The engine room 1 d is disposed below the rear deck 1 g.

The radar arm 1 e of the small watercraft 1 is provided with a radar (not illustrated) and supports the radar.

The radar arm 1 e is integrally formed with the hull 1 a.

The radar arm 1 e is formed to have an arch shape. The radar arm 1 e extends from an upper end from the hull 1 a in an inclined manner in an upper rear direction, and surrounds side portions of the deck 1 b, rear side portions of the cabin 1 c, and a rear upper portion of the cabin 1 c.

The air introduction ports if of the small watercraft 1 are used for introducing intake air for the engine into the engine room 1 d in the inboard section from the outside.

In the small watercraft 1, the air introduced into the inboard section through the air introduction ports if is supplied to the engine room 1 d through piping (not illustrated).

As illustrated in FIG. 11A, the rear deck 1 g is disposed in a stern portion and more on a rear side than the cabin 1 c, and thus the rear deck 1 g is disposed above the engine room 1 d. An opening 1 m, communicating with the engine room 1 d, is formed in an approximately center portion of the rear deck 1 g. The rear deck 1 g is provided with a flap door 41 that can be opened and closed to close the opening 1 m. In other words, the small watercraft 1 has the flap door 41 of the rear deck 1 g serving as a top board of the engine room 1 d. Thus, in the small watercraft 1, maintenance work for the engine 23 in the engine room 1 d can be performed while the flap door 41 of the rear deck 1 g is in the open state.

The flap door 41 can be opened and closed by raising and lowering the bow side of the flap door 41 about a hinge 41 a, provided at an end portion on the stern side, serving as a rotational axis. The bow side end portion of the flap door 41 is connected to an electric cylinder 42 provided in the engine room 1 d. The flap door 41 can be opened and closed through extension and contraction of the electric cylinder 42.

A trench 1 n is formed at an edge portion over the entire circumference of the opening 1 m on an upper surface of the rear deck 1 g. The trench 1 n has a shape similar to the flap door 41, and a size large enough to fit the flap door 41 with a gap in between. The trench 1 n is formed to have a depth that is approximately the same as the thickness of the flap door 41. Thus, the trench 1 n supports the flap door 41 in such a manner that the upper surface of the rear deck 1 g is flush with the upper surface of the flap door 41 covering the opening 1 m. As illustrated in FIG. 11B, the trench 1 n and a groove 1 p of the rear deck 1 g may have bent end portions.

The transom gate 1 h of the small watercraft 1 is disposed in the stern side rear end portion. The transom gate 1 h is formed as a part of a transom surrounding the rear deck 1 g.

As illustrated in FIG. 12, the transom gate 1 h is rotatable. The transom gate 1 h is used as a path to move from the small watercraft 1 to a land (for example, a pier) by being rotated to be laid rearward.

Next, a configuration of an inboard section of the small watercraft 1 will be described in detail.

As illustrated in FIGS. 9 and 10, the small watercraft 1 includes inboard compartments.

The outlet 56 may be disposed on both starboard and port sides in the owner room 3. The cabinet 56 d is disposed on a rear-starboard side in the owner room 3.

The bow side windows 13 a of the side windows 13 are disposed on side surfaces of the owner room 3 on the starboard and port sides. The front roof window 11 is disposed at approximately the center of the ceiling of the owner room 3. Thus, the daylighting in the owner room 3 with sunlight can be achieved through the bow side windows 13 a of the side windows 13 formed on the hull 1 a and the front roof window 11 formed on the deck 1 b.

As described above, the owner room 3 is the compartment that is curved in accordance with the shape of the hull 1 a, and has the side surfaces provided with the inner wall materials 54. Thus, in the small watercraft 1, the space of the inboard section can be more effectively used, so that the owner room 3 can have a larger space (living space) compared with a configuration in which walls (inner wall materials) stand vertically in the inboard section. The unillustrated audio device and the operation device 56 a for the audio device are embedded in the side surface of the owner room 3. Thus, the small watercraft 1 needs no inboard space for placing the audio device and the operation device 56 a for the audio device, whereby the inboard space can be effectively used, so that the owner room 3 can have a larger space (living space).

The inner wall materials 54 of the owner room 3 of the small watercraft 1 include a cushion material.

The owner room 3 has a plurality of the inner wall materials 54 (cushion materials) that are long in the bow and stern direction arranged in the upper and lower direction in a clinker built fashion.

The owner room 3 is formed with the plurality of inner wall materials 54, including the cushion materials, arranged in the upper and lower direction in the clinker built fashion as described above. Thus, in the small watercraft 1, the inboard space can be effectively used, so that the owner room 3 can have a larger space (living space). Furthermore, the owner room 3 with a better appearance can be achieved.

The owner room 3 is formed with a plurality of beam members 55 exposed in the owner room 3 in the inboard section (side portions of the inboard section). The owner room 3 is provided with the beam members 55 arranged at a predetermined interval in the bow and stern direction in the watercraft.

The small watercraft 1 with the owner room 3 as a compartment provided with the beam members 55 exposed in the owner room 3 can have a strength improved with the beam members 55 exposed in the owner room 3 unlike in the configuration where the beam members 55 are hidden to make the space of the owner room 3 smaller.

As illustrated in FIGS. 15 and 16, a lighting device 57 is disposed at an approximately center portion in the upper and lower direction of each of the beam members 55 that are disposed to be exposed in the owner room 3 of the small watercraft 1.

In the small watercraft 1, the owner room 3 can be made bright by daylighting through the front roof window 11.

The small watercraft 1 includes the side windows 13, on the side portions of the deck 1 b, having the bow side windows 13 a on the left and right sides of the owner room 3 and the stern side windows 13 b disposed on the salon 4 and the galley 5. Thus, in the small watercraft 1, the owner room 3, the salon 4, and the galley 5 can be made bright by daylighting through the side windows 13.

In the small watercraft 1, the salon 4 and the galley 5 can be made bright by daylighting through the rear roof window 12 and the pair of left and right stern side windows 13 b. The small watercraft 1 has the rear roof window 12 that is openable and closable and thus can be used for ventilating the compartments, for going to and coming back from the bow deck (deck 1 b), or the like.

As illustrated in any one of FIGS. 1 to 5, 7, 9, 13, and 20, the small watercraft 1 includes the cabin 1 c provided with the windshield 14, the pair of left and right side windows 15, 15, and the window door 45 serving as the gateway 1 i. The windshield 14 is disposed at a front portion of the cabin 1 c and the side windows 15, 15 are disposed at the side portions of the cabin 1 c. The windshield 14 is disposed on the front side of the helmsman seat 21 a, and the side windows 15, 15 are respectively disposed on the left and the right sides of the helmsman seat 21 a. The cabin 1 c of the small watercraft 1 is provided with the glassed window door 45, serving as the gateway 1 i to the rear deck 1 g, on the stern side. The window door 45 is disposed at the stern side end portion of the cabin 1 c and serves as a partition from the rear deck 1 g.

The small watercraft 1 includes the pilot house 2 and the lounge space 8 that are surrounded by the windshield 14, the pair of left and right side windows 15, 15, the movable roof 16, and the window door 45. Thus, in the small watercraft 1, the helmsman seat 21 a and the lounge space 8 can be made bright by daylighting through the windshield 14, the pair of left and right side windows 15, the movable roof 16, and the window door 45. Furthermore, the guest room 6 can be made bright by the daylighting through the skylight 2 c.

As illustrated in any one of FIGS. 9, 13, and 20, the pilot house 2 and the lounge space 8 of the small watercraft 1 are disposed in the same space with no partitioning wall separating one from the other provided in between. The helmsman seat 21 a in the pilot house 2 is movable in the upper, lower, front, and rear directions. The helmsman seat 21 a in the pilot house 2 is rotatable by 360° to adjust the orientation (the orientation of the driver in charge of steering sitting on the helmsman seat 21 a). In the small watercraft 1, the helmsman seat 21 a is oriented toward the bow side when the steering of the small watercraft 1 is performed. The helmsman seat 21 a in the pilot house 2 rotated to be oriented to the lounge space 8 (for example, rotated by 180° from the bow side) faces the sofa 67 and the table 68 in the lounge space 8.

In the small watercraft 1 in which the pilot house 2 and the lounge space 8 are disposed in the same space and the helmsman seat 21 a in the pilot house 2 rotated to be oriented toward the lounge space 8 faces the sofa 67 and the table 68 in the lounge space 8 as described above, the helmsman seat 21 a in the pilot house 2 rotated to be oriented toward the lounge space 8 faces the sofa 67 and the table 68 in the lounge space 8, and thus the table 68 in the lounge space 8 can be surrounded by the helmsman seat 21 a in the pilot house 2 and the sofa 67 in the lounge space 8.

Thus, the pilot house 2 and the lounge space 8 can each have a compact structure in the small watercraft 1 without compromising the functionality, whereby the space in which the pilot house 2 and the lounge space 8 are formed can be effectively used.

The pilot house 2 of the small watercraft 1 further includes the assistant helmsman seat 21 b that is disposed next to (on the left side of) the helmsman seat 21 a, movable in the upper, lower, front and rear directions as in the case of the helmsman seat 21 a, and rotatable by 360°.

The assistant helmsman seat 21 b in the pilot house 2 rotated to be oriented toward the lounge space 8 faces the sofa 67 and the table 68 in the lounge space 8.

As described above, the seats in the pilot house 2, that is, the assistant helmsman seat 21 b and the helmsman seat 21 a in the pilot house 2 rotated to be oriented toward the lounge space 8 face the sofa 67 and the table 68 in the lounge space 8. Thus, in the small watercraft 1, the table 68 in the lounge space 8 can be surrounded by the helmsman seat 21 a and the assistant helmsman seat 21 b in the pilot house 2, and the sofa 67 in the lounge space 8.

As illustrated in FIGS. 1 to 10, the small watercraft 1 is relatively long on the bow side as viewed from the pilot house 2.

Thus, the small watercraft 1 can have a space large enough to dispose the front roof window 11 and the rear roof window 12 (space large enough to arrange the two roof windows on the deck 1 b in the bow and stern direction).

In addition, the pair of left and right side windows 13 of the small watercraft 1 can be made large in the bow and stern direction.

Furthermore, the owner room 3, the guest room 6, the salon 4, the galley 5, and the shower room 7 of the small watercraft 1 can be made wide in the bow and stern direction.

As illustrated in FIG. 23, the small watercraft 1 may include a seat 19 and a backrest 20 in the stern portion. The seat 19 in the small watercraft 1 is detachably attached to the rear deck 1 g and the backrest 20 is detachably attached to an inner wall of the transom.
